Definitions

  • the present invention relates in general to multi-contact switching devices, and more particularly to improvements in relay structures by means of which different contact positions are accomplished through successive operations of the relay.
  • Such a relay structure finds many uses in circuit combinations wherein intermediate sequential operations are required in order to realize a desired over-all result.
  • An object of the invention is to provide a new and novel relay structure which embodies a simple, compact and inexpensive construction.
  • Another object of the invention is to provide an improved relay arrangement wherein a contact does not operate during a first energization of the relay: wherein the contact operates responsive to a following de-energization of the relay: wherein the operated contact remains undisturbed during a re-energization of the relay; and wherein the operated contact is restored to its normal position responsive to a second deenergization of the relay.
  • a further object of the invention is to provide a new and novel relay structure whereby a contact is operated each time the relay is energized and is restored to its normal position each time the relay is tie-energized; whereby a second contact remains in its normal position during a first energization of the relay and is operated responsive to a following de-energization of the relay; and whereby the operated second contact is restored to its normal position responsive to a de-energization of the relay following a re-energization of the relay.
  • a feature of the invention resides in the interposing of a new and novel mechanism between the armature of the relay and a contact switch unit for controlling the operation of the contact switchunit in response to successive operations of the armature.
  • Another feature of the invention concerns the new and novel manner in which the mechanism interposed between the armature of the relay and a contact switch unit functions to cause the operation of the contact switch unit only when a first restoration of the armature is accomplished, and to cause the restoration of the operated contact switch unit only when a second restoration of the armature is accomplished.
  • a further feature of the invention relates to a novel adjusting arrangement for regulating the operation of the mechanism interposed between the armature of the relay and a contact switch unit.
  • Fig. 1 is a top, or plan, view of the relay showing particularly the arrangement of the two operating arms of the armature and the associated contact springs comprising right and left switch units.
  • Fig. 2 is a right-hand side view, in elevation, of the relay showing another view of the right-hand switch unit of Fig. 1 and the parts of a lever mechanism for operating this switch unit which are not obscured by the cover plate located on the right-hand side of the relay.
  • Fig. 3 is a left-hand side view, in elevation, of the relay showing another view of the left-hand switch unit of Fig. 1 and the armature arm for operating same.
  • Fig. 4 is an end view, in elevation, of the relay showing further details of the armature and the two switch units.
  • Fig. 5 is a fragmentary right-hand side view of the relay, similar to the lower part of Fig. 2 with the cover plate removed.
  • Fig. 5 shows details of the bracket attached to the relay heel piece for mounting the lever mechanism required for operating the switch unit of Fig. 2.
  • Fig. 6 is a left-hand side view, in elevation, of the mounting bracket shown in Fig. 5, illustrating how the mounting bracket is attached to the relay heel piece.
  • Fig. 7 is a fragmentary end view of the mounting bracket taken along the line .'7 in Fig. 5.
  • Fig. 8 is a cross-section taken along the line 38 in Fig. 5, showing further details of the mounting bracket.
  • Fig. 9 is a right-hand side view of the relay showing the armature, the right-hand switch unit of Fig. 1 and the lever mechanism controlled by the armature for operating the right-hand switch unit, all in the normal, or non-operated, positions.
  • Fig. 10 is a right-hand side View of the relay showing the relationship of the armature, the lever mechanism and the right-hand switch unit after the first energization of the relay. It should be observed that the armature has moved to the operated position and that the switch unit still remains in the normal, or non-operated, posi- Fig. 11 is a right-hand side View of the relay showing how the lever mechanism automatically operates the right-hand switch unit as the armature restores to the normal position following the first de-energization of the relay. The righthand switch unit, however, remains in the operated position and is not disturbed by the restoration of the armature.
  • Fig. 12 is a right-hand side view of the relay showing the relationship of the armature, the lever mechanism and the right-hand switch unit after the second energization of this relay.
  • the armature has again moved to the operated position but the right-hand switch unit-remains in the operated position of Fig. 11.

  • a downwardly bent tab 18 is formed integrally with washer is and extends through a recess (not shown) in yoke l into an aligned opening (not shown) in heel piece I2 in a well-known manner to prevent relative motion between yoke 55 and heel'piece 12.
  • pivot pin l6, yoke and screw I! are formed of non-magnetic material in order to prevent these elements from interfering with the magnetic flux path between armature l3 and heel piece l2. Any of the well-known residual means can be utilized for preventing armature 13 from sticking to core [0.
  • armature 13 carries a pair of spaced apart and inwardly directed arms [9 and disposed on the oppositesides of heel piece 12 and provided with aligned holes therein which receive the opposite outer ends of pivot pin M, the opposite outer ends of pivot pin i s being flanged over inorder to rigidly secure pivot pin I 4 to arms Iii and 20 and, consequently, to armature l3.
  • arm I9 is provided with an inturned operating projection 2i (Fig. 1) which overlies the top surface of heel piece l2 and co-operates with contactswitch unit 22 carried by heel piece 12.
  • can be fitted with a residual (not shown) or any well-known residual means can be used for preventing projection 2
  • Armature 13 further carries an arm 23 and a pushing member 45 (Figs. 2 and 4) for co-operating with the lever mechanism mounted on the righthand side of the relay (the lever mechanism is mostly concealed by cover 24 in Fig. 2 but may be observed in detail in Figs. 9 to 12, inclusive), the lever mechanism co-operating with contact switch unit 25 of the relay in the manner to be described in later paragraphs.
  • Switch units 22 and 25 comprise a plurality of individual flexible metallic switch, or contact, springs such as 25, 2?, 28, 29 arranged in two pile-ups, each pile-up being secured to heel piece l2 by a pair of screws 38. More specifically, the base ends of the contact springs in each pile-up are spaced apart and insulated from each other by a plurality of interposed insulating pieces 3
  • the contact springs need not be of the particular type or form shown in the drawings but may be of any well-known form, according to circumstance or preference. Also, the number of contact springs and the particular contact combination of each switch unit may be varied to suit any requirement.
  • a substantially L-shaped bracket 33 for mounting the previously mentioned lever mechanism is rigidly attached to heel piece 52 by means of screws 3:3 or other suitable means.
  • Tapped bosses 35 on bracket 33 and screws 36 (Fig. 2) provide means for attaching cover 2 3 to retain the various levers of thelever mechanism in their respective positions.
  • Projections 3?, 38, 39 and 4% of bracket 33 provide bearing means for the various levers of the lever mechanism.
  • the lever'mechanism for controlling switch unit 25 comprises four interlinked levers ll, 42, ":3 and i4 controlled by armature it through the medium of arm 23 and adjustable pushing member 55.
  • levers til, 42, 53 and i i are formed of non-magnetic material in order to cause no irregular operation.
  • lever ll is substantially L- shaped, the left-hand half of its horizontal member being bearinged by bracket 33 and projections 37 and 38 extending therefrom, the right-hand end of the horizontal member being guided by U-sliaped projection 39.
  • Helical spring as seated against projection 3:) and acting on shoulders ll and or" the horizontal member keeps the vertical member of lever A l firmly against pushing member 45 of armature arm 23 at all times.
  • lever G2 is of the bell-crank type, bearinged on bracket 33 by pivot pin 59.
  • One end of a flat spring 51 is fixedly attached to the upper arm of lever 32 in any suitable manner, the other end of spring 5i resting against lower projection 52 of lever 3d.
  • causes the lower arm of lever 22 to bear down on stop stud 53 of lever (it (Fig. 9) thereby to retain lever is in its lower position.
  • the lower arm of lever 22 has a shoulder 5 normally restin against projection 55 of lever ti. and the upper arm of lever 5,2 is notched at 53.
  • lever G3 is also of the bell-crank type, bearinged on lever i l by pivot pin 5?.
  • Helical spring 52 attached to the right-hand arm of lever 33 at 59 and to stud 56 of lever td-causes the tip of the right-hand arm of lever l3 to rest on the upper arm of lever 32 just clear of notch 53 (Fig. 9) and the tip of the lower arm of-lever 43 to clear projection 33 of bracket 33.
  • lever Al is of the sliding typeand is located in the central portion bracket 33, the upper end of the lever passing over cutout Bl of bracket 33, and the central portion of the lever being bearinged by inwardly turned projections 33.
